The situations aren't really any different. Nothing in his life has changed yet, but this is just the first "rich" person moving into the neighborhood. Just as one example, in many business cultures it isn't acceptable for a manager to make less than the people under their direction; it is also often true that all promotion paths lead into management. In these cases lower relative pay means you're not getting promoted. Even though you might be happy with the job you have now, that doesn't mean "get promoted" isn't on the list somewhere.
